Multiple Land Administration Domain Model (LADM) related studies have been carried out in two decades. ISO 19152 LADM is an international standard and an abstract, conceptual model covering the land administration domain (including those over land and water and elements above and below the earth's surface). The LADM is considered an important component for managing and developing land administration systems worldwide. In the context of this study's, scientific publications related to LADM are examined to carry out a bibliometric analysis on LADM research from 2012 to 2020. The extent of this investigation is limited to the Scopus database for scientific publications. All databases belong to the most extensive peer-reviewed summary and citation databases. It is noted that this study is based on the same principles as the research published by Paulsson and Paasch (2015), building on existing knowledge and aiming to add value in support to the current development of Edition II of the LADM. In this study, which covers 2012–2020, 175 LADM related scientific publications were found in the Scopus database. When the distribution of publications in journals is examined, Land Use Policy has the most published manuscripts related to ISO 19152 LADM. This analysis considers author identification, type of paper, organisational issues, and bibliometric analysis components. The analysis considered articles, books, and proceedings directly related to the LADM and included in the Scopus database or conference and workshop proceedings. For this, articles and books were selected from the Scopus database. Also, the proceedings were selected from those presented in the International Federation of Surveyors (FIG) events and workshops on LADM. Overall, this paper aims to arrange and present the global scientific production on LADM-based research.@en

Type people to land relations are dynamic and, as a consequence, the nature of land title and cadastral data is of a dynamic nature. Land title and cadastral data are core components for a lot of property applications (e.g. taxation, valuation, mortgage). Those applications require up to date, complete and reliable data–including temporal data as in use in application forms and transactions. In this paper, the modelling of Rights, Restrictions and Responsibilities (RRR) is discussed with a focus on the modelling of easement rights in a case study in Turkey. Functional requirements with respect to the characteristics of easement rights are investigated based upon interviews with professional experts in the public and private sector. Then a prototype model was built based on a simple implementation of the Land Administration Domain Model (LADM) RRR classes and by conforming to the national cadastral data management standards related to land registration systems. This new proposed model includes temporal cadastral attributes related to easements. This is materialised in the ‘Administrative Package’ and illustrated in the Turkey LADM country profile. We show that the LADM can be used to describe for the time dimension of cadastral information in Turkey, but that there are semantic differences, similarities and mismatches of classes and attributes between the LADM and the cadastral information system in Turkey. Proposed LADM-based model for the time dimension of cadastral information will be of immense advantage to land administrators, the governments and land users in Turkey.@en
